lVhen the machine is con operation .of its perte 111" yfollows: The

of the frame. The 'plates 5 are recessed to admit the beam plates and toforni the inside vertical supporting surface jfor the lower beam. 16also exten'ds over but clears the bars 13. The supporting points of theplates 16 are 1 on the bars 17. The bed 18 on which the dies are securedis placed between the plates v,16 on which lit rests.

formed by the plates described is secured rlhe lower beam `in place bythe plates 14. The vertical adjustment of this lower beam is effected bythe movement ofthe screws 10 and 11, by which the wedges slidable oneach other and between the top of the blocks 7 on which they rest, andthe bar 13.0n which the completed beam is carried. `The upperv 'beamconsists of the plates .20 and 21 and 23. These plates are inserted'inthe frame in the. same way as the lowerbeam. The

. plates 19 are secured in position; the eccentric' connecting rods 31are placed in positionv on the shaft 30 and in the bearings 25.

y AThe parts 29 are secured to the plates 20 and 21.' The' connectingrods 27 are placed in shallowbore in the heads of the eccentricconnecting rods 31 and in the like recesses in the blocks 26. The screws28 are then adjusted to thrust the head of the rods into close movablecontact .with the blocks 25.. When the parts are so connected, therotationof the shafts operate the connecting lro'ds 31. The downwardthrust of these rods on the bearing blocks 25tixed in the plates 20 and21' force down those plates and the die plate 24, by which the-materialinserted between the dies secured on the die plates- 18 and'24 isformed, cut or pierced. -The upward movement of the rods 31 actingthroughthe connecting rods 27 and blocks 26 lifts the plates 20, 21 and24. The screws 28 are adapted to take up all lost motion 'betweenybearing blocks 25 and head of the rods 31.

What I claim as new and desire to secure byl Letters Patent is:

1. In a machine of the kind described, the

combination with a frame consisting of two pairs of end plates, `theplates ofeach pair being spaced; of adjustable means secured plates,adjustable means secured to said.

plates adapted to support the lower beam of said machine; of a lowerbeam consisting of two outside plates adapted to rest ver- The upperpart of the plates tically on said supporting means, and two innerplates supported. vertically on two transverse bars extending throughsaid outer and inner plates, said inner plates being adapted to supporta die plate above said outer plates as described.

3. In a..maclhii`ie of the kind described the combination with a frame,and adjustable l means therein adapted to support the lower beam; of alower beam consistingof a plurality of plates adapted to rest on saidsupporting means in said frame, and a plurality of plates adapted tosupport a die plate, said plurality of plates being supported by saidfirst mentioned plates, and means adapted to form the supportingconnection between said supporting and supported plates.

` beam consisting of two outer plates and two inner plates, said platesbeing disposed vertically in relation to said frame and Vto each other,means adaptedto secure said outer plates to said frame, and meanswhereby said inner plates can be connected together and means adapted tomove said inner plates vertically between' said outer plates, said innermovable plates being adapted to support a die plate. i

6. In a machine of the kind described, the combination with a fra-me anda lower die plate beam supported therein; of an upper beam consisting ofa pluralityA of plates vertically disposed in. said frame, a part ofsaid plates being xfed in said frame, and the other part being connectedtogether amd movable vertically between said xed plaftesf and meansadapted to move said connected plates as described, said movable plateslaeing adapted to support a die plate.

7 In a machine of the kind described, thev combination with a frame anda lowerA die plate beam supported therein, and an upper beam consistingof a plurality of outer plates iixed'in said frame, and inner platesmovable vertically. between said outer plates, and means adapted to movesaid linner plates; of adjustable means connectingsaid inner plates andsaid means for moving said plates, as described. l

8. In a machine of the kind described, the combination*consisting of aframe, a lower die plate supporting beam consisting of outer platessupported in Said frame and inne? plates supported by said outer plates,

l n a i l move said lnner plates, and means adapted means aclapte t0adjust said beam in said to adjust the positions of said beams inrelaconsisting of outer and inner plates, said outer plates being ixedin said frame, and said inner plates being movable vertically betweensaid outer plates, means adapted to frame, an upper die platesupportixigibea'm tion to each other as described.
